Add a personal server access on your account

Usage: --osh SCRIPT_NAME --host HOST [OPTIONS]

  --host IP|HOST|IP/MASK   Server to add access to
  --user USER              Remote login to use, if you want to allow any login, use --user-any
  --user-any               Allow access with any remote login
  --port PORT              Remote SSH port to use, if you want to allow any port, use --port-any
  --port-any               Allow access to all remote ports
  --scpup                  Allow SCP upload, you--bastion-->server (omit --user in this case)
  --scpdown                Allow SCP download, you<--bastion--server (omit --user in this case)
  --force                  Add the access without checking that the public SSH key is properly installed remotely
  --force-key FINGERPRINT  Only use the key with the specified fingerprint to connect to the server (cf selfListEgressKeys)
  --ttl SECONDS|DURATION   Specify a number of seconds (or a duration string, such as "1d7h8m") after which the access will automatically expire
  --comment "'ANY TEXT'"   Add a comment alongside this server. Quote it twice as shown if you're under a shell.
